French reported another train had just arrived, containing well and wounded prisoners, paroled and non-paroled together, of whom it was necessary to send all who could travel to Fort McHenry. A medical officer was immediately sent to make the selections, which duty is not yet completed.

The difficulty lies, first, in sending mixed parties of prisoners without notifications (which is beyond the control of this office), and, secondly, the failure of the railroad company to transfer the men to their proper destination, which this office can only remedy by the continuance of representations similar to those it has repeatedly made already.

For those wounded who are now in Fort McHenry it will require, I presume, the authority of the commanding general for their transfer to West's Hospital.

I have the honor to be, colonel, very respectfully, your obedient servant,

J. SIMPSON,

Surgeon, U. S. Army, Medical Director.
